An essential diagnostic tool for testing potentially faulty electro mechanical relays. This tool tests both 12V / 24V relays, with four / five pins (not late model Ford 4 pin).

Simply plug the relay into the tester - using 12V vehicle power, the relay will be cycled 10 times with the tester applying a signal to the relay coil while checking the function of the internal contacts. The tester applies load to the internal contacts to detect excessive resistance.

• Quickly test 3 common types of electro mechanical relays
• Test relay coil resistance / relay contacts / cyclic testing
• Relay coil resistance: 20 - 500 Ohms
• Test voltage for coil: 9V
• Contact resistance threshold: 200 milliohms
